We successfully generate ionic liquid incorporated plasmas at low gas pressures with high stability, similar to normal glow discharge plasmas. Figure 3 shows the photos of the stable DC discharge plasma in A-mode in the regions below the anode electrode and above the...

The photos of the discharge plasma in B-mode in the regions below the cathode and above the anodes as a function of gas pressure Pgas are given in Fig. 4. The cathode glow is observed below the cathode electrode and its volume becomes small with an increase in the gas pressure in the same way as the case of A-mode. Since the mean free path becomes short with an increase in the gas pressure, the electrons accelerated by the cathode sheath collide with the neutral gas closer to the cathode electrode, and then the glow region is considered to shrink.
